How to Change Dyson Filter Air Purifier in 2026: A Quick Guide

Let’s be honest—air purifiers are one of those home appliances we tend to forget about… until we notice the air doesn’t feel as fresh, or worse, we start sneezing more than usual. I remember the first time I realized my Dyson air purifier wasn’t working as well as it used to. I’d been using it daily for over a year, and one morning, I walked into the living room and caught a whiff of something musty. That’s when it hit me: the filter probably needs changing.

It’s easy to overlook maintenance, especially when your Dyson purifier runs quietly in the background, doing its job without fanfare. But just like your car needs an oil change or your phone needs a software update, your air purifier needs regular care—especially the filter. In 2026, with more of us spending time indoors and air quality concerns on the rise, keeping your Dyson filter fresh isn’t just a nice-to-have—it’s essential. And the good news? Changing the filter is simpler than you might think. Whether you’re a first-time Dyson owner or you’ve been using one for years, this guide will walk you through every step, so you can breathe easy knowing your air is truly clean.

Why Changing Your Dyson Filter Matters

Think of your Dyson air purifier’s filter like the lungs of your home. It’s constantly pulling in air, trapping dust, pollen, pet dander, smoke, and even microscopic pollutants like VOCs (volatile organic compounds). Over time, that filter gets clogged. It’s doing its job—but it’s also working harder, which means your purifier isn’t as efficient. And if you don’t change it, you might actually be breathing in partially filtered or even re-circulated dirty air.

How Often Should You Change the Filter?

Dyson recommends replacing the filter every 12 months under normal usage. But “normal” can vary. If you live in a city with high pollution, have pets that shed, or suffer from allergies, you might need to change it sooner—maybe every 6 to 9 months. On the flip side, if you only use your purifier occasionally or live in a rural area with cleaner air, you might stretch it closer to 18 months. The key is to pay attention to your environment and how your purifier performs.

Signs It’s Time for a New Filter

You don’t always need to wait for the yearly mark. Here are a few telltale signs your Dyson filter needs replacing:

• Reduced airflow: If the purifier isn’t pushing out as much air as it used to, the filter might be clogged.
• Unusual odors: A musty or burnt smell often means the filter is saturated and can’t trap smells effectively.
• Increased allergy symptoms: More sneezing, coughing, or itchy eyes? Your filter might not be capturing allergens like it should.
• Filter indicator light: Many Dyson models have a filter life indicator that turns red or flashes when it’s time for a change.

I learned this the hard way. After ignoring a faint burning smell for a week, I finally checked the filter—and it was black and packed with dust. Changing it immediately made a noticeable difference in air quality and the purifier’s performance.

Types of Dyson Air Purifier Filters

Not all Dyson filters are the same. Depending on your model, you might have a HEPA filter, a carbon filter, or a combination of both. Understanding what you’re working with will help you choose the right replacement and maintain your purifier effectively.

HEPA Filters: The Allergen Blockers

HEPA stands for High-Efficiency Particulate Air. These filters are designed to capture 99.97% of particles as small as 0.3 microns—think pollen, dust mites, mold spores, and even some bacteria. If your Dyson model includes a HEPA filter (like the Dyson Purifier Cool or Hot+Cool), this is the main line of defense against airborne irritants.

One thing to note: Dyson uses a glass HEPA H13 filter in many of its newer models. This is a higher-grade filter than standard HEPA, offering even better filtration. It’s sealed in a plastic casing, which means you don’t have to handle the delicate filter material directly—just remove the whole unit.

Carbon Filters: Odor and Gas Fighters

While HEPA filters catch particles, carbon filters are all about gases and odors. They’re made from activated carbon, which has a porous structure that traps smoke, cooking smells, pet odors, and VOCs from cleaning products or furniture. If your Dyson model has a carbon filter (often labeled as “activated carbon” or “charcoal”), it’s usually located behind or alongside the HEPA filter.

Carbon filters don’t last as long as HEPA filters because they can become saturated with gases. That’s why Dyson often combines both in a single filter unit—so you replace them together, even if one might still have life left.

Combined Filters: The All-in-One Solution

Many Dyson air purifiers, like the Purifier Humidify+Cool or Purifier Hot+Cool Formaldehyde, use a combined HEPA + carbon filter. This simplifies maintenance—you only need to replace one unit instead of two. These filters are typically housed in a removable cassette that clicks in and out easily.

Pro tip: Always check your model number before buying a replacement. Dyson filters are model-specific. For example, the filter for a Dyson TP04 is different from a TP07, even though they look similar. Using the wrong filter can reduce performance or even damage your machine.

Step-by-Step Guide to Changing Your Dyson Filter

Now for the main event: actually changing the filter. Don’t worry—it’s not complicated. Most Dyson purifiers are designed for easy maintenance, and you don’t need any special tools. Here’s how to do it, step by step.

Step 1: Turn Off and Unplug the Purifier

Safety first. Always turn off your Dyson air purifier and unplug it from the wall before doing any maintenance. This prevents accidental activation and protects you from electrical hazards. I made the mistake of changing a filter while the machine was in standby mode once—let’s just say the sudden blast of air was… surprising.

Step 2: Locate the Filter Compartment

The filter compartment is usually at the base of the purifier. Look for a circular or rectangular panel with a latch or release button. On models like the Dyson TP04 or TP07, it’s on the back, near the bottom. On the Dyson HP04 or HP07 (Hot+Cool models), it’s on the front, behind a removable grille.

If you’re not sure, check the user manual or look for a small icon of a filter on the machine. Dyson also includes a filter release button or lever—press or slide it to open the compartment.

Step 3: Remove the Old Filter

Once the compartment is open, gently pull out the filter cassette. It should slide out smoothly. Some models have a handle or grip area—use that to avoid touching the filter material directly. If the filter is stuck, don’t force it. Double-check that the release mechanism is fully engaged.

When removing the old filter, be careful not to shake it too much. You don’t want to release trapped dust and allergens back into the air. I recommend doing this near a trash can or outside if possible.

Step 4: Insert the New Filter

Take your new Dyson filter out of the packaging. Make sure it’s the correct model—compare the part number on the box with the one on your old filter. Most Dyson filters have a label like “304093-01” or “304100-01.”

Slide the new filter into the compartment, making sure it’s seated properly. You should hear a soft click when it’s in place. Don’t force it—if it doesn’t go in easily, double-check the orientation. Some filters are directional and only fit one way.

Step 5: Close the Compartment and Reset the Filter Life

Once the new filter is in, close the compartment securely. Make sure the latch clicks shut. Then, plug the purifier back in and turn it on.

Here’s a crucial step many people skip: reset the filter life indicator. On most Dyson models, you can do this through the Dyson Link app or by holding down a specific button combination on the machine (usually the “Oscillation” and “Power” buttons for 5–10 seconds). This tells the purifier the filter is new and resets the countdown to 12 months.

Skipping this step means your purifier might still show a “filter change” warning, even though you’ve already replaced it. I’ve seen this happen more than once—don’t let it happen to you!

Tips for Maintaining Your Dyson Air Purifier

Changing the filter is important, but it’s just one part of keeping your Dyson air purifier in top shape. Regular maintenance can extend the life of your machine and ensure it’s always working at peak efficiency.

Clean the Exterior and Vents

Dust and dirt can build up on the outside of your purifier, especially around the air intake and output vents. Use a soft, dry cloth to wipe down the surface weekly. For tougher grime, lightly dampen the cloth with water—never spray liquid directly on the machine.

Pay special attention to the loop amplifier (the ring-shaped part that blows air). Dust can accumulate here and affect airflow. A microfiber cloth or a small brush works well for getting into tight spaces.

Check the Oscillation and Fan Mechanism

If your purifier oscillates (moves side to side), make sure the mechanism isn’t obstructed. Sometimes pet hair or fabric fibers can get tangled in the base. Turn off and unplug the machine, then gently clean around the rotating parts with a dry brush or compressed air.

Also, listen for unusual noises—grinding, clicking, or rattling. These could indicate a mechanical issue that needs attention. If the fan seems sluggish, it might be due to dust buildup inside, which may require professional servicing.

Use the Dyson Link App for Monitoring

If your Dyson model is app-enabled (like the TP04, TP07, or HP07), download the Dyson Link app. It tracks air quality in real time, shows filter life, and sends reminders when it’s time for maintenance. You can also control the purifier remotely, set schedules, and monitor pollutant levels like PM2.5 and VOCs.

I’ve found the app incredibly helpful. It once alerted me to a spike in indoor pollution after I painted a wall—something I wouldn’t have noticed otherwise. The purifier automatically increased its fan speed, and within an hour, the air was back to normal.

Avoid Common Mistakes

Here are a few things to avoid:

• Using third-party filters: While cheaper, non-Dyson filters may not fit properly or meet the same performance standards. Stick with genuine Dyson replacements.
• Overloading the purifier: Don’t run it 24/7 at maximum speed unless necessary. This wears out the filter faster and increases energy use.
• Ignoring the filter light: That little red light isn’t nagging—it’s helping. Replace the filter when prompted.
• Storing the purifier improperly: If you’re not using it for a while, store it in a dry, dust-free place with the filter removed or sealed in a plastic bag.

Choosing the Right Replacement Filter in 2026

With so many Dyson models on the market, finding the right filter can feel overwhelming. But it doesn’t have to be. Here’s how to make sure you get the correct one.

Check Your Model Number

The easiest way to find the right filter is to look up your purifier’s model number. It’s usually on a label on the base or back of the machine. Common models include:

• TP04 (Purifier Cool)
• TP07 (Purifier Cool Formaldehyde)
• HP04 (Purifier Hot+Cool)
• HP07 (Purifier Hot+Cool Formaldehyde)
• PH01 (Purifier Humidify+Cool)

Once you have the model number, search for “Dyson [model number] filter” on the Dyson website or authorized retailers like Amazon, Best Buy, or Home Depot.

Understand Filter Variants

Some models have multiple filter options. For example, the TP07 uses a filter that captures formaldehyde—a harmful gas found in some building materials and furniture. If you don’t have formaldehyde concerns, you might opt for a standard HEPA + carbon filter, but Dyson recommends using the formaldehyde version if your model supports it, as it’s more advanced.

Also, note that some filters are labeled “long-life” or “extended.” These are designed to last longer but may cost more upfront. Consider your usage and air quality needs when choosing.

Where to Buy Genuine Dyson Filters

Always buy from reputable sources. Counterfeit filters are a real problem and can damage your purifier or reduce performance. Stick to:

• The official Dyson website
• Authorized retailers (check Dyson’s store locator)
• Well-reviewed sellers on Amazon (look for “sold by Dyson” or “fulfilled by Amazon”)

Prices typically range from $60 to $90 per filter, depending on the model. While it’s an added expense, think of it as an investment in your health and home air quality.

Frequently Asked Questions (Without Being a FAQ Section)

Over the years, I’ve heard a lot of questions from friends and online communities about Dyson filter changes. Let me share a few insights based on real experiences.

Can I clean and reuse the filter? No. Dyson filters are not washable. Attempting to rinse or vacuum them can damage the delicate fibers and reduce effectiveness. Always replace with a new one.

What if my purifier doesn’t have a filter light? Older models or basic versions might not have a filter indicator. In that case, mark your calendar for a yearly change or monitor performance closely.
